Member Function Documentation

AddStatusFiles()

bool AddStatusFiles ( std::vector< pkgIndexFile * > &  List )

overridevirtual

Implements pkgSystem.

ArchitecturesSupported()

std::vector< std::string > ArchitecturesSupported ( ) const

overridevirtual

architectures supported by this system

A MultiArch capable system might be configured to use this capability.

Returns

a list of all architectures (native + foreign) configured for on this system (aka: which can be installed without force)

Implements pkgSystem.

ArchiveSupported()

APT_PURE bool ArchiveSupported ( const char *  Type )

overridevirtual

Implements pkgSystem.

CreatePM()

pkgPackageManager * CreatePM ( pkgDepCache *  Cache ) const

overridevirtual

Implements pkgSystem.

FindIndex()

bool FindIndex ( pkgCache::PkgFileIterator  File, pkgIndexFile *&  Found  ) const

overridevirtual

Implements pkgSystem.

Initialize()

bool Initialize ( Configuration &  Cnf )

overridevirtual

Reimplemented from pkgSystem.

IsLocked()

bool IsLocked ( )

overridevirtual

checks if the system is currently locked

Implements pkgSystem.

Lock()

bool Lock ( OpProgress *  Progress )

overridevirtual

Implements pkgSystem.

LockInner()

bool LockInner ( OpProgress *const  Progress, int  timeoutSec  )

overridevirtual

Implements pkgSystem.

MultiArchSupported()

bool MultiArchSupported ( ) const

overridevirtual

Todo:

these methods should be virtual

does this system has support for MultiArch?

Systems supporting only single arch (not systems which are single arch) are considered legacy systems and support for it will likely degrade over time.

The default implementation returns always true.

Returns

true if the system supports MultiArch, false if not.

Implements pkgSystem.

Score()

signed Score ( Configuration const &  Cnf )

overridevirtual

Reimplemented from pkgSystem.

UnLock()

bool UnLock ( bool  NoErrors = false )

overridevirtual

Implements pkgSystem.

UnLockInner()

bool UnLockInner ( bool  NoErrors = false )

overridevirtual

Implements pkgSystem.
